With high uptime and minimal breakage rate the TS240C is designed to work reliable 24h/7.The semi automatic tabber and stringer unit is configured to operate where precision is required, and where expensive fully automation is not feasible.

It most likely not clever to use 230 V rms but should use and build a 12 V dc system. But the TV may become a problem due to it's high power consumption.But are you aware of the fact that a 50 W dc module will not (constantly) provide 50 W, even in Africa? You could obviously be happy when it generates 250 Wh per day, minus about 20% losses for charging results in maybe 200 Wh daily use, so a 50 W load may run 4 hours. But that would require the accumulator to be bigger than 50 Ah without any safety margin for even a single day not being sunny. Because a single small 50 Wp module might by far not be sufficient (as probably e.g. mobiles also want to get charged).

Now the plant has problems: the energy production of the first year was 3000 kWh (good) but the energy of the second year was about 2150 kWh and the energy production continously go down.I'm in contact with E3 company that propose me to accept money to consider the plant downgrade 10%.I know that in the past WURTH replaced the modules but now the new society offers money upon agreement.

I'd like to know the situation in Germany: do somebody give me some info?Is the production of the CIS modules terminated?

A spokesperson told pv magazine that the law has already been given internal approval by the council, but still needs to be officially recognized

The new law has to be implemented by the EU member states within 18 months after it comes into effect.Changes such as:- separating modules from other electrical products- separate collecting of modules - strengthening of existing collection and recycling structures

The U.S. Department of Energy’s National Renewable Energy Lab (NREL) confirmed the record, which eclipsed the prior record of 13.4 percent, which also was set by First Solar.

This is interesting news. We'll see, how things will develop. If FS can achieves its goals for 2015 (15% efficiency modules), than CdTe can become hard competitor to c-Si. If the price will be competitive!

The price for the complete investment costs is estimated at around $1/Wp. The ThinFab production line is further said to increase manufacturing line output, guarantee higher module efficiency and have a newer narrow-gap design for silicon deposition, according to a spokesperson of Oerlikon.

The photon's energy is transmitted to an electron. If the electron energy is large enough, then it leaves the semiconductor. The contacts on the top of the cell now collect the electrons. The current can now flow back through the cable into the cell.

Schott Solar advised that it had achieved 20.2% efficiency on its monocrystalline screen-printed solar PV cell; a feat that was confirmed by the Fraunhofer Institute for Solar Energy Systems (ISE). The 4.92W cell uses an industrial sized 156mm x 156mm wafer, which led Schott to maintain that this is the first PV cell of its size to reach this efficiency.

Unfortunately, there is still no information on prices. Is this the way to force the high efficiency market leader (Sunpower and Sanyo) at reasonable module prices?

So it sometimes is hard to find the right module for users. Therefore we provide an expert search that helps you to find your module.If you click on the screenshots, they will be displayed in a higher resolution in a new window.

Here's how to proceed:

Step 1:Click on "Module database" on the top of the page

step 1.jpg

Step 2:Now you either can search by selecting letters of the alphabet (if you know the manufactureres name) or click on "Expert search" as displayed on the following screenshot.

step 2.jpg

Step 3: Now you get several options (see screenshot)These are:search by - keyword - manufacturer - module type - production - nominal power manufactuerer information - etc.Then press "Go" and view the results on the following page.You can choose up to 4 different search charakteristics. Use the drop-down buttons to change the charakteristics.

Caution: If you enter a keyword, you can not custom the other search options any more

step 3.jpg

Step 4:Now you can further modify your results by sorting them by one of the selected charakteristics. Therefore just click on the fitting headline. Now the results will be sorted.The charakteristics in the headlines are the same you have chosen in step 3. step 4.jpg

Step 5: Choose the fitting modules and enjoy.
